微型微机械催化气体传感器在功耗和响应时间方面具有很大的优势。与多孔催化剂层结合，可以实现高灵敏度。然而，这种方法通常不能提供足够的长期稳定性。本文提出了一种基于胶体制备和稳定的铂纳米颗粒作为催化层的小型化氢气检测催化气体传感器。由于其小型化设计和高度多孔的催化剂，
Miniaturized micro-machined catalytic gas sensors offer great advantages regarding power consumption and response time. In combination with a porous catalyst layer high sensitivity can be achieved. However, often this approach does not provide sufficient long-term stability. In this article a miniaturized catalytic gas sensor for hydrogen detection is presented based on colloidally prepared and stabilized platinum nanoparticles as a catalytic layer. Due to its miniaturized design and the highly porous catalyst, a very short response time of
